LLU Institutional Review Board Application Materials “Multiple Risk Factor Analysis in an Outpatient, Intensive Lifestyle Modification Program” A. BACKGROUND AND RATIONALE Summary This pilot research project is a 15-day outpatient, intensive lifestyle modification program in which a group of approximately 20 patients will receive multiple lifestyle interventions including dietary and exercise programs, health lectures, cooking classes, physical therapy and outings to a natural setting. The 15-day program will be followed by a one-year lifestyle support program with periodic evening meetings. Background The majority of the deaths in the United States each have are lifestyle related. There would be a large improvement in the health of the public if they were to personally adopt healthy lifestyles. Numerous studies illustrate the significant impact that lifestyle modifications can make on patients with lifestyle diseases. With its Seventh-day Adventist (SDA) heritage, Loma Linda University has long had a special emphasis on the role of lifestyle in health. In numerous places throughout the United States and the rest of the world, SDAs have implemented intensive lifestyle modifications programs; many of which are inpatient. Such programs last about 18 days and have found significant improvements in systolic blood pressure, weight, treadmill endurance, cholesterol, triglycerides, fasting blood sugar, diabetic neuropathy and angina. Whereas these programs achieve impressive short-term clinical results they are often located in areas that are remote from large population centers and therefore have difficulty with follow-up support of the patient's new lifestyle. Additionally, the programs tend to be fairy expensive with a large portion that needs to be covered out-of-pocket by the patients themselves. This tends to significantly limit the market for such services. Loma Linda University and Medical Center have a number of lifestyle intervention programs such as cardiac rehabilitation, the Diabetes Center and several programs offered through the Center for Health Promotion. However they do not offer the intensive lifestyle, group interventions provided by the intensive lifestyle modification programs. The research project here proposed will attempt to determine if an outpatient intensive lifestyle modification program based at Loma Linda will be able to achieve short-term clinical results. B. Study Objectives To assess the effectiveness of an outpatient, intensive lifestyle modification program in treatment of lifestyle-related illnesses such as type 2 diabetes, hypertension, obesity and dyslipidemia. C. Procedures Involved The only procedures utilized will be a standard venipuncture performed at the LLU Medical Center laboratory as well as standard exercise stress tests performed at the Center for Health Promotion. Lifestyle interventions will be discussed in the methodology section. Experimental Portion The experimental portion of this project will be the lifestyle interventions provided to patients. This will include dietary and exercise programs, health lectures, cooking classes, physical therapy and outings to a natural setting. A one-year lifestyle support program with periodic evening meetings will follow the 15-day program. Statistical Justification As this is a pilot research project, it will be used to investigate the effect size necessary for a power calculation so that the number of patients needed can be determined for subsequent investigations. Human subject involvement Eligibility or inclusion criteria for cases are that they have been diagnosed with at least one of several lifestyle diseases, have been seen by their primary physician for these diseases at least three times in the 12 months prior to the study and have signed permission by their primary care physician for participation. Subjects will pay $2,500 for the services provided in the program. Medical charts will have to be available and subjects will consent to participate in the study. Diagnosed lifestyle diseases used in this study include chronic lifestyle diseases such as type 2 diabetes, hypertension, obesity, and hyperlipidemia. Exclusion criteria include all those with angina (stable or unstable), previous MI or stroke within the last 3 months, CABG within the last 12 months, and any other life-threatening conditions detected on history, physical, exercise stress test or lab tests. Subjects will also be excluded from the study if they have a disability that would not allow participation in all aspects of the intervention. Patients who desire to participate in the program but do not wish to participate in the study or who are excluded from the study will be treated in the LLLP in a manner no different than any of the research subjects. Recruitment Subjects will be recruited through direct mailings from local medical clinics as well as printed and broadcast advertisements. Consent Subjects will be provided the attached consent form as well as the California Experimental Subject’s Bill of Rights. These will be provided on the first day of the 15-day intensive portion of the program. A project staff member in the Center for Health Promotion will discuss these materials with each subject thoroughly and confidentially. Methodology The LLLP will be based on the campus of Loma Linda University under the administration of the Center for Health Promotion (CHP). The CHP will be utilized for history and physicals, in-depth dietetic, exercise and psychological evaluations as well as the exercise stress tests and clinic visits. Other on-campus facilities will be utilized for other portions of the program. Subjects will also be transported to several natural settings for exercise using LLU vehicles and appropriately licensed drivers. LLLP’s Lifestyle interventions will be those commonly used by preventive care providers. These include health education, exercise and dietary changes including cooking classes. Physical therapists and exercise physiologists for the purpose of addressing orthopedic problems affecting exercise as well as promoting stress reduction will provide additional interventions. These will include routine stretching activities prior to exercise, application of localized and general hot and cold water, massage and range-of-motion exercises. Specific therapies will be provided under the prescription of the program’s medical director. Measurements of height, weight, hip/waist ratios, blood pressure, CBC, chemistry panel (including electrolytes, LFTs, TSH and lipid profile), homocysteine and c-reactive protein will be obtained at the initial and final evaluations of subjects in the CHP. Exercise stress tests will be conducted at the CHP before and after the 15-day intervention. During the initial evaluation, subjects will meet one-on-one with a dietician for evaluation of the subjects’ diets. During the 15-day program subjects will receive 36 meals including 8 take-home meals. All meals will be prepared on-site. Meals will be vegetarian with high-complex carbohydrate, high-fiber and zero-cholesterol. Caloric intake will not be less than 1200 cal/day. Dietary fat will be approximately 25% with emphasis on mono-unsaturated fats. Subjects will also receive 8 lectures on nutrition and will participate in 11 cooking classes. Subjects will also be provided with a vegetarian cookbook. Subjects will initially be evaluated regarding their exercise history and will be evaluated by a team of physical therapists and exercise physiologists. Preventive Care faculty and students will perform an exercise stress test prior to an at the end of the 15-day program. This will assess exercise tolerance as well as screen for cardiac conditions. An exercise prescription of gradually increasing moderate exercise will be developed for each subject’s specific condition. Subjects will receive one lecture on exercise. During the 16-day program they will participate in 24 observed exercise sessions and routine stretching activities associated with exercise. Subjects will receive physical therapy to assist with orthopedic conditions (e.g. arthritis), to assist circulation and reduce stress. Therapy will vary between patients according to their specific needs but may include range-of-motion exercises, application of localized and general hot and cold water, and massage. All smoking subjects will be encouraged to quit prior to the start of the 15-day program. Nicotine replacements and/or buproprion will be prescribed for those subjects needing these. All subjects will be encouraged to eliminate sources of caffeine. Subjects will also be encouraged to discontinue alcohol and to reduce cardiac risks by lifestyle changes. They will also receive a lecture regarding the need for abstinence form harmful substances. Subjects will be encouraged to drink 6-8 glasses of water a day. They will be provided with ready access to bottled water and will be provided with sports bottles. They will also receive a health lecture on the benefits of water consumption. Stress management will be taught in lecture and practice will be encouraged including adequate rest and exercise, proper breathing and meditating on and trust in divine help. During the 15-day program, subjects will be managed clinically under the direction of the medical director. Clinical interventions will include adjustment of those medications related to the lifestyle diagnoses. Should a subject need treatment for a medical condition unrelated to the LLLP, they will be referred to their primary physician. Nurses will daily monitor the condition of subjects. This will include daily vitals and finger stick blood sugars two to four times daily if appropriate. Nurses will also be continually available to subjects while on campus and available by phone when subjects are at home. Should any situation arise requiring prompt clinical attention, the nurse will be in ready contact with the medical director. Medical records of the patients’ evaluations, history and physicals, daily nursing records and final clinical report will be kept at the Center for Health Promotion. Copies of the final clinical report will be forwarded to the subjects’ primary care physician. Finally, the program will attempt to provide an environment conducive to the subjects making fundamental lifestyle changes. The program staff will seek to develop friendly relationships with and around the subjects. Music, social interaction, natural settings, recreation, humor and a spiritual environment will all be used to create a supportive environment for subjects. D. Alternative Procedures The treatment in this project is not intended to be an alternative to the ongoing care that subjects will already be receiving through their primary care or specialty physician. Treatment provided will be in addition to and in cooperation with their treating physicians. E. Deception No deception will be needed or utilized in this research project. F. Literature Review Wellness programs are a structured intervention focused on achieving wellness in the physical, psychological or spiritual realm (Watt, Verma, Flynn, 1998). These programs are aimed at helping patients to improve their quality of life as well as their physical health through the use of exercise, diet, and/or spirituality. As such, wellness programs may be an effective way of improving the treatment of chronic illnesses (Watt, Verma, Flynn, 1998). Various wellness programs are in operation in different settings (Watt, Verma, flynn, 1998). Many wellness programs do show that wellness programs improve the quality of life and physical health. Conrad and Gibbs, 1988 showed that the effects of their wellness program had a positive impact on health outcomes. The study assessed the impact of health promotion on employee risk factors, absenteeism, and insurance utilization per site. The results indicated that participants of the program exhibited reduced blood pressure, decreased serum cholesterol, loss of weight, and increased smoking cessation rate compared to non-participants. In another study, Bowne et al, 1984 showed an improvement in the level of cardio-respiratory fitness from baseline measurements to the one-year follow-up for the participants of the fitness program at the Southwestern Home Office. The proportion of participants in the combined high and good categories increased from 16.9% to 39.1%, while the proportion in the low and fair categories decreased from 56.2% to 33.7%. Another benefit of wellness program includes increased work productivity as evidenced by a study by Holzbach, Piserchia, McFadden(in press) examined the effect of comprehensive health promotion program on “work related attitudes” of employees at Johnson & Johonson. The results indicated significant positive changes on organizational commitment, surpervision, working conditions, job competence/security, and pay/benefits for participants of the health promotion program. The benefits of wellness programs not only include increasing physical health but also saving medical cost in the long run. The healthcare expenditures in the United States reached $322 billion in 1982, or over 10% of the gross national product. (Bowne, 1984). With this rate of increase in health care costs, economists predict that costs will double every five years at the current rate of escalation. With the increase of interest in wellness and health by the public and skyrocketing of health care costs, it makes a good sense to come up with ways to reduce the rising health care costs. One of the ways that shows a promise of reducing the health care costs is through wellness programs (Bowne, 1984). Wellness programs that incorporate various aspects of health promotion such as exercise, diet, and spirituality may be one of the answers to rising health care costs. Pellitier (1991) pointed out that comprehensive health promotion programs are both health and cost-efffective. In the last decade, there has been a recognition that the strategy of wellness and lifestyle modification holds a promise of decreasing health care costs (Bowne et al, 1984).
